BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a vaporization device and a methodthereof, and more particularly to an electronic device providing aninhalable aerosol and a method thereof.

2. Description of the Related Art

An electronic cigarette is an electronic product that heats avaporizable solution and vaporizes the solution to produce an aerosolfor a user to smoke.

In recent years, major manufacturers begin to produce various electroniccigarette products. Generally, an electronic cigarette product includesa housing, an e-liquid storage chamber, an vaporization chamber, aheating component, an air inlet, an airflow channel, an air outlet, apower supply device, a sensing device and a control device. The e-liquidstorage chamber is configured to store a vaporizable solution, and theheating component is used to heat and vaporize the solution to generatean aerosol. The air inlet is in communication with the vaporizationchamber, and provides air to the heating component when the userinhales. The aerosol generated by the heating component is firstgenerated in the vaporization chamber, and subsequently inhaled by theuser via the airflow channel and the air outlet. The power supply devicesupplies power needed by the heating component, and the control devicecontrols the heating time of the heating component according to aninhalation action of the user detected by the sensing device. Thehousing wraps all the foregoing components.

Existing electronic cigarette products have different defects, which mayresult from poor designs of relative positions between differentmembers. For example, common electronic cigarette products are designedto align the heating component, the airflow channel and the air outletin a vertical direction. Since the airflow has a specific length, theaerosol is cooled when passing through the airflow channel, and acondensed liquid is formed on the airflow channel wall. Under thisdesign, when the condensed liquid reaches a specific volume, the user islikely to inhale the condensed liquid directly and consequently have abad experience of choking.

In addition, existing electronic cigarette products are not designed toavoid countercurrent flow of condensate. When the electronic cigaretteis tilted or placed upside down, the condensed liquid remaining in thevaporization chamber and the airflow channel may leak from the air inletor the air outlet. The leaking condensed liquid may damage electricalcomponents (for example, the sensing device and the control device) inthe electronic cigarette product.

Further, existing electronic cigarette products are not designed tocontrol the power output of the heating component. When the user inhalesfor a long time, the power supply device continuously heats the heatingcomponent, and the heating component may be overheated and produce aburnt smell, causing a bad experience for the user. The overheatedheating component may also destroy or burn the internal components ofthe electronic cigarette. Fast power consumption is also a generaldisadvantage of existing electronic cigarette products that are notdesigned to control the output power.

Therefore, a vaporization device and a method thereof are provided toresolve the foregoing problems.

As shown in FIG. 3A, the cartridge housing 3 includes an e-liquidstorage compartment 30, an air inlet channel 31 and an air outletchannel 32. In some embodiments, the air inlet channel 31 and the airoutlet channel 32 may be located inside the cartridge housing 3. In someembodiments, the air inlet channel 31 and the air outlet channel 32 maybe defined by an internal structure of the cartridge housing 3. In someembodiments, the air inlet channel 31 and the air outlet channel 32 maybe defined by the cartridge housing 3 and the body housing 24 together.In some embodiments, the air inlet channel 31 may be defined by theinternal structure of the housing 3 and the heating component base 8together. In some embodiments, the air outlet channel 32 may be definedby the internal structure of the housing 3 and the heating componentbase 8 together.

The air inlet channel 31 is located on one side of the cartridge housing3, and the air outlet channel 32 is located on the other side of thecartridge housing 3. In some embodiments, the air inlet channel 31 maybe located on one side of the heating component 6, and the air outletchannel 32 may be located on the other side of the heating component 6opposite to the air inlet channel 31.

In some embodiments, the pipe diameter of the air inlet channel 31 maybe the same as that of the air outlet channel 32. In some embodiments,the pipe diameter of the air inlet channel 31 may be different from thatof the air outlet channel 32. In some embodiments, the pipe diameter ofthe air inlet channel 31 may be smaller than that of the air outletchannel 32.

In some embodiments, the sensor startertube 7 and the heating component base 8 may be made of a same material.In some embodiments, the sensor starter tube 7 and the heating componentbase 8 may be made of different materials.

As shown in FIG. 3B, the length of the air inlet channel 31 is 31L, andthe length of the air outlet channel 32 is 32L. In some embodiments, thelength 31L may be different from the length 32L. In some embodiments,the length 31L may be less than the length 32L.

The length 7L and the length 31L may be in a proportional relationship.In some embodiments, a proportion of the length 31L and the length 7Lmay be within a range of 6 to 7. In some embodiments, a proportion ofthe length 31L and the length 7L may be within a range of 7 to 8.

The air outlet channel 32is in communication with the outside through a through hole 1 h on themouthpiece 1. In some embodiments, the through hole 31 h and the throughhole 1 h are located in different positions in the horizontal direction.In some embodiments, the distance between the through hole 31 h and theheating component 6 is different from the distance between the throughhole 1 h and the heating component 6. In some embodiments, the distancebetween the through hole 31 h and the heating component 6 is less thanthe distance between the through hole 1 h and the heating component 6.

The e-liquid storage compartment 30 is a sealed area. The e-liquidstorage compartment 30 may be formed by compartment structures 30 w 1and 30 w 2 in the cartridge housing 3 and the heating component top cap4. A part where the heating component top cap 4 makes contact with thecompartment structures 30 w 1 and 30 w 2 has a sealing member 4 r. Thesealing member 4 r makes the heating component top cap 4 and thecompartment structures 30 w 1 and 30 w 2 closely in contact with eachother.

The part of the air outlet channel 32 incommunication with the through hole 1 h of the mouthpiece 1 has adirection change 3 f 5.

FIG. 4 shows an airflow direction generated when the user inhales fromthe cartridge 100A. When the user inhales, air enters from a gap betweenthe cartridge 100A and the body housing 24, and experiences thedirection change 3 f 1 between the cartridge 100A and the body housing24. Subsequently, the air enters the air inlet channel 31 through thethrough hole 31 h, and experiences the direction change 3 f 2 beforeentering the vaporization chamber 8 c.

An airflow 7 f is generated in the sensor starter tube 7 by theinhalation action of the user. The airflow 7 f enters the cartridge 100Afrom the sensor starter tube 7. In some embodiments, the airflow 7 f mayenter the air inlet channel 31. In some embodiments, the airflow 7 f mayenter the vaporization chamber 8 c with the inhalation action of theuser. In some embodiments, part of the airflow 7 f may enter the airoutlet channel 32 with the inhalation action of the user.

The airflow 7 f is detected by the sensor 16 when passing through a gapbetween the cartridge 100A and the body 100B. The controller 171activates the heating component 6 based on a detection result of thesensor 16, and generates an aerosol in the vaporization chamber 8 c. Thegenerated aerosol experiences the direction change 3 f 3 when theaerosol just enters the air outlet channel 32. The generated aerosolsubsequently experiences the another direction change 3 f 4 at thethrough hole 1 h in the air outlet channel 32 close to the mouthpiece 1.The generated aerosol experiences the another direction change 3 f 5when leaving the through hole 1 h on the mouthpiece 1.

When the vaporization device 100 is being used, the aerosol may condenseinto a liquid 32 d and remain on an inner wall of the air outlet channel32. The condensed liquid 32 d is viscous and does not easily flow on theinner wall of the air outlet channel 32. When the user is inhaling, theplurality of direction changes 3 f 3, 3 f 4 and 3 f 5 included in theair outlet channel 32 may preferably prevent the condensed liquid 32 dfrom being inhaled by the user through the through hole 1 h.

The airflow has a temperature rise Tr after passing through thevaporization chamber 8 c from the air inlet channel 31. In someembodiments, the temperature rise Tr may be within a range of 200° C. to220° C. In some embodiments, the temperature rise Tr may be within arange of 240° C. to 260° C. In some embodiments, the temperature rise Trmay be within a range of 260° C. to 280° C. In some embodiments, thetemperature rise Tr may be within a range of 280° C. to 300° C. In someembodiments, the temperature rise Tr may be within a range of 300° C. to320° C. In some embodiments, the temperature rise Tr may be within arange of 200° C. to 320° C.

An airflow from the vaporization chamber 8 c may has a temperature dropTf before reaching the through hole 1 h. The airflow from thevaporization chamber 8 c may has a temperature drop Tf when passingthrough the air outlet channel 32. In some embodiments, the temperaturedrop Tf may be within a range of 145° C. to 165° C. In some embodiments,the temperature drop Tf may be within a range of 165° C. to 185° C. Insome embodiments, the temperature drop Tf may be within a range of 205°C. to 225° C. In some embodiments, the temperature drop Tf may be withina range of 225° C. to 245° C. In some embodiments, the temperature dropTf may be within a range of 245° C. to 265° C. In some embodiments, thetemperature drop Tf may be within a range of 145° C. to 265° C.

In some embodiments, the aerosol inhaled by the user via the throughhole 1 h can have a temperature below 65° C. In some embodiments, theaerosol inhaled by the user via the through hole 1 h can have atemperature below 55° C. In some embodiments, the aerosol inhaled by theuser via the through hole 1 h can have a temperature below 50° C.

FIG. 5A and FIG. 5B are sectional views of a cartridge according to someembodiments of the present invention.

As shown in FIG. 5A, a blocking component 33 a may be disposed in theair inlet channel 31. The blocking component 33 a may have a throughhole 33 h. A diameter of the through hole 33 h is smaller than the pipediameter of the air inlet channel 31. The through hole 33 h may beregarded as a portion of the air inlet channel 31. The thickness of theblocking component 33 a is 33L. The thickness 33L of the block component33 a results in a height drop in the air inlet channel 31. Since theliquid or the e-liquid stored in the e-liquid tank 8 t is viscous, theheight drop facilitates preventing the liquid or the e-liquid stored inthe e-liquid tank 8 t from flowing backwards. The height dropfacilitates preventing the liquid or the e-liquid stored in the e-liquidtank 8 t from leaking via the through hole 31 h.

In some embodiments, the block component 33 a may be made of silica gel.In some embodiments, the block component 33 a may be a silicone ring. Insome embodiments, the block component 33 a and the housing 3 may be madeof a same material. In some embodiments, the block component 33 a andthe housing 3 may be made of different materials. In some embodiments,the block component 33 a and the housing 3 may be two separatecomponents. In some embodiments, the block components 33 a and thehousing 3 may be formed integrally.

As shown in FIG. 5B, a blocking component 33 b may be disposed in theair inlet channel 31. The blocking component 33 b may cause the air toenter the air inlet channel 31 through the through hole 31 h. The blockcomponent 33 b may prevent the liquid from flowing from the e-liquidtank 8 t to the through hole 31 h. In some embodiments, the blockcomponent 33 b may be a check valve.

A blocking component 34 may be disposed in the air outlet channel 32.The blocking component 34 may have one or more through holes 34 h. Theblocking component 34 may cause the aerosol to flow from thevaporization chamber 8 c to the through hole 1 h. Since the liquid ore-liquid stored in the e-liquid tank 8 t is viscous, the hole diameterof the through hole 34 h is designed to prevent the liquid or thee-liquid from flowing from the e-liquid tank 8 t to the through hole 1h.

FIG. 6A, FIG. 6B, FIG. 6C, FIG. 6D and FIG. 6E are top views of aheating component top cap according to some embodiments of the presentinvention.

The e-liquid stored in the e-liquid storage compartment 30 may makecontact with the heating component 6 through a through hole 4 h on theheating component top cap 401 and a through hole 5 h on the siliconeheating component seal member 5.

The hold diameter and shape of the through hole 4 h may be adjustedaccording to the property of the e-liquid. In some embodiments, if theviscosity of the e-liquid is relatively high, the hole diameter of thethrough hole 4 h can be designed relatively big. In some embodiments, ifthe viscosity of the e-liquid is relatively low, the hole diameter ofthe through hole 4 h can be designed relatively small. The through hole4 h with a relatively small hole diameter may prevent excessive e-liquidfrom making direct contact with the heating component 6. The throughhole 4 h with a relatively big hole diameter may ensure more e-liquid tomake direct contact with the heating component 6.

The hole diameter of the through hole 4 h may be appropriately adjustedaccording to the property of the e-liquid, so that the heating component6 can make contact with enough e-liquid to avoid dry burning duringheating and prevent the generated aerosol from having a burnt odor.

The hole diameter of the through hole 4 h may be appropriately adjustedaccording to the property of the e-liquid to prevent the heatingcomponent 6 from making contact with excessive e-liquid. The excessivee-liquid cannot be adsorbed by the heating component 6, and graduallypermeates from the e-liquid storage compartment 30 to the e-liquid tank8 t through the heating component 6. If the amount of e-liquidpermeating into the e-liquid tank 8 t is excessively large, theprobability of the e-liquid flowing into the air inlet channel 31 andthe air outlet channel 32 will increase. If the amount of e-liquidpermeating into the e-liquid tank 8 t is excessively large, theprobability of the e-liquid permeating out of the through hole 31 h ofthe air inlet channel and the through hole 32 h of the air outletchannel will increase.

FIG. 10 is a flowchart of an output power control method according tosome embodiments of the present invention.

The output power control method 200 may include a plurality of steps. Insome embodiments, the steps in the output power control method 200 maybe performed sequentially in the order shown in FIG. 10. In someembodiments, the steps in the output power control method 200 may not beperformed in the order shown in FIG. 10.

Step 201: Detect an inhalation action of the user. The Step 201 may beperformed by a sensor 16 and a controller 171 in combination.

Step 202: Determine whether a duration in which a power outputted to theheating component 6 is stopped is greater than a threshold TN1. If thetime when an output power to the heating component 6 is stopped isgreater than or equal to the threshold TN1, Step 203 is performed. Ifthe time when an output power to the heating component 6 is stopped isless than the threshold TN1, Step 204 is performed. Step 202 may beperformed by setting a timer in the controller 171. A timer may be setin the controller 171, and starts when the power supply component 20stops provide power for the heating component 6.

In some embodiments, the threshold TN1 is within a range of 15 secondsto 60 seconds. In some embodiments, the threshold TN1 is within a rangeof 25 seconds to 40 seconds. In some embodiments, the threshold TN1 maybe 30 seconds.

Step 203: Output a power P1 to the heating component 6 in a duration S1,and output a power P2 to the heating component 6 in a duration S2 afterthe duration S1. The duration S1 and the duration S2 are both during thecontinuous inhalation action of the user. Step 204 may be performed bythe controller 171, a circuit board 17, a power supply component 20, aconductive contact 9, a conductive probe 15 and the heating component 6in combination.

In some embodiments, the power P1 may be greater than the power P2. Insome embodiments, P1 is within a range of 6 W to 15 W. In someembodiments, P1 is within a range of 7.2 W to 9 W. In some embodiments,P2 is within a range of 4.5 W to 9 W. In some embodiments, P2 is withina range of 6 W to 8 W.

In some embodiments, S1 is within a range of 0.1 second to 2 seconds. Insome embodiments, S1 is within a range of 0.1 second to 1 seconds. Insome embodiments, S1 is within a range of 0.1 second to 0.6 seconds.

In some embodiments, S2 is within a range of 0.1 second to 4 seconds. Insome embodiments, S2 is within a range of 0.1 second to 3.5 seconds.

Step 202 and Step 203 have a plurality of advantages. Whether thevaporization device 100 has not been in use for a long time can bedetermined by the threshold TN1. The heating component 6 appears in acool state when the user has not used the vaporization device 100 for along time. When the user performs a first inhalation action to thevaporization device 100, the vaporization device 100 may output arelative high power P1 in the duration S1. The relative high power P1may accelerate the generation of an aerosol. When the inhalation actionof the user lasts for the duration S2, the heating component 6 alreadyhas a specific temperature, and the vaporization device 100 can reducethe output power to P2. The reduced power P2 may allow the aerosol to begenerated uniformly. The reduced power P2 may increase the use time ofthe power supply component 20.

Step 204: Output a power P3 to the heating component. Step 203 may beperformed by the controller 171, the circuit board 17, the power supplycomponent 20, the conductive contact 9, the conductive probe 15 and theheating component 6 in combination.

In some embodiments, P3 is within a range of 3.5 W to 10 W. In someembodiments, P3 is within a range of 4.5 W to 9 W. In some embodiments,P3 is within a range of 6 W to 8 W. In some embodiments, P3 and P2 maybe the same. In some embodiments, P3 and P2 may be different.

Step 202 and Step 204 have a plurality of advantages. Whether thevaporization device 100 has been used by the user in a short time can bedetermined by the threshold TN1. If the vaporization device 100 has beenused by the user in a short time, the heating component 6 has not beencooled completely. If the vaporization device 100 has been used by theuser in a short time, the heating component 6 has a specifictemperature. In this case, the vaporization device 100 may adjust theoutput power to P3. The adjusted power P3 allows the aerosol to begenerated uniformly. The adjusted power P3 may increase the use time ofthe power supply component 20.

Step 205: Stop outputting the power to the heating component when theduration of outputting the power to the heating component has reachedthe threshold TN2. Step 205 may be performed by setting a timer in thecontroller 171.

Step 205 has many advantages. When the time of the heating component 6being continuously heated has reached the threshold TN2, the stop ofheating may prevent the heating component 6 from being overheated.Overheated heating component 6 may damage another component inside thevaporization device 100. Overheated heating component 6 may decreaseservice lives of components inside the vaporization device 100. When thetime of the heating component 6 being continuously heated has reachedthe threshold TN2, the stop of heating may prevent the heating component6 from dry burning. Drying burning the heating component 6 may produce aburnt odor. Drying burning the heating component 6 may produce toxicchemicals.

In some embodiments, the threshold TN2 is within a range of 2 seconds to10 seconds.

Step 206: The vaporization device 100 is triggered to enter a standbystate when a duration in which the inhalation action has not beendetected reaches a threshold TN3. When staying in the standby state, thepower consumption of the vaporization device 100 is reduced. Whenstaying in the standby state, the sensor 16 remains in an active state.Step 206 may be performed by setting a timer in the controller 171.

When the user stops inhaling, the output power control method 200 mayfurther include a step of stopping outputting power to the heatingcomponent 6. The step may be performed by the sensor 16 and thecontroller 171 in combination.
